ZTX795ASTOB Equivalent & Substitute Parts

Part Overview

The ZTX795ASTOB is a Bipolar (BJT) Transistor, PNP type, manufactured by Diodes Incorporated. This component is rated for 140 V collector-emitter breakdown voltage with a maximum collector current of 500 mA and 1 W power dissipation. The device features a transition frequency of 100 MHz and operates across a temperature range of -55°C to 200°C. The ZTX795ASTOB is packaged in an E-Line-3 (TO-92 compatible) through-hole configuration with formed leads.

The ZTX795ASTOB is classified as an obsolete product. Locating equivalent or substitute parts becomes necessary when the original component is no longer available from primary sources or when design requirements necessitate components with active product status and improved supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ZTX795ASTOB is determined by electrical and mechanical parameter equivalence. The following parameters establish the substitution criteria:

Electrical Parameters:

• Transistor Type: PNP
• Maximum Collector Current (Ic): 500 mA
• Maximum Collector-Emitter Breakdown Voltage: 140 V
• Vce Saturation: 250 mV @ 50 mA, 500 mA
• Maximum Collector Cutoff Current (ICBO): 100 nA
• Minimum DC Current Gain (hFE): 300 @ 10 mA, 2 V
• Maximum Power Dissipation: 1 W
• Transition Frequency: 100 MHz
• Operating Temperature Range: -55°C to 200°C

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: E-Line-3, Formed Leads
• Supplier Device Package: E-Line (TO-92 compatible)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must match all electrical specifications and maintain mechanical compatibility with the E-Line-3 through-hole package configuration. Packaging format (tape & box versus individual packaging) does not affect electrical or mechanical substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The ZTX795ASTZ is a direct electrical and mechanical equivalent to the ZTX795ASTOB. All critical electrical parameters, including collector current rating, breakdown voltage, saturation characteristics, current gain, power dissipation, and frequency response, are identical. The devices share the same E-Line-3 through-hole package configuration and are pin-compatible.

The primary distinction between these parts is product status and packaging format. The ZTX795ASTOB is classified as obsolete, while the ZTX795ASTZ maintains active product status. Both components are ROHS3 compliant and carry identical moisture sensitivity ratings.

The ZTX795ASTZ is supplied in Tape & Box (TB) packaging format, whereas the ZTX795ASTOB was supplied in individual packaging. This packaging difference does not affect electrical performance or mechanical compatibility. The tape and box format is standard for active production components and provides equivalent component integrity.

For applications requiring the ZTX795ASTOB, the ZTX795ASTZ provides full functional and mechanical substitution with the advantage of active product availability and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Are the ZTX795ASTOB and ZTX795ASTZ electrically identical?

A: Yes. Both devices are PNP Bipolar (BJT) Transistors with identical electrical specifications: 140 V maximum collector-emitter breakdown voltage, 500 mA maximum collector current, 1 W power dissipation, 100 MHz transition frequency, and 300 minimum DC current gain at specified conditions. Operating temperature ranges and saturation characteristics are identical.

Q: Can the ZTX795ASTZ be used as a direct replacement for the ZTX795ASTOB in existing circuit boards?

A: Yes. Both components use the E-Line-3 through-hole package with formed leads in E-Line (TO-92 compatible) configuration. Pin assignments and mechanical dimensions are identical, enabling direct substitution in through-hole PCB designs without layout modifications.

Q: What is the difference between the ZTX795ASTOB and ZTX795ASTZ?

A: The primary differences are product status and packaging format. The ZTX795ASTOB is obsolete and was supplied in individual packaging. The ZTX795ASTZ is an active product supplied in Tape & Box (TB) format. All electrical and mechanical specifications are identical.

Q: Why is the ZTX795ASTZ supplied in Tape & Box packaging?

A: Tape & Box (TB) packaging is the standard format for active production components. This packaging method provides efficient handling, storage, and automated assembly compatibility while maintaining component integrity and moisture protection equivalent to individual packaging.

Q: Are both parts RoHS compliant?

A: Yes. Both the ZTX795ASTOB and ZTX795ASTZ are ROHS3 compliant and carry identical moisture sensitivity ratings of MSL 1 (Unlimited).

Q: Can I use the ZTX795ASTZ in high-temperature applications?

A: Yes. The ZTX795ASTZ operates across the full temperature range of -55°C to 200°C (junction temperature), identical to the ZTX795ASTOB. This range supports both cryogenic and elevated-temperature applications within the specified limits.

Q: What is the transition frequency of the ZTX795ASTZ?

A: The transition frequency is 100 MHz, identical to the ZTX795ASTOB. This specification defines the frequency at which the transistor's current gain drops to unity and is relevant for high-frequency switching and amplification applications.
